|Computer Simulation of Fresnel Diffraction from Triple Apertures by Iterative Fresnel Integrals Method - Fatema Hamid Al-Saiari, S.M. Mujibur Rahman, Kazi Monowar Abedin|
The Iterative Fresnel Integrals Method (IFIM) has been applied for the simulation and generation of the complete near-field Fresnel diffraction images created by triple apertures for the first time. The simulation can be performed in any PC using an included MATLAB program. Necessary formalism has been derived and simulation algorithm has been developed for this application. An interesting combination of interference effects with Fresnel diffraction has been observed in the simulation images...

|User support services and network application development: An overview - Gary, J. Patric|
An overview is given of the user support services and network application development. The overview consists of the background, elements of NASA Science Internet (NSI) with GSFC responsibility, GSFC element objectives, and a summary of current status and plans. A conclusion of the overview is that refinement to the objectives and plans of the NSI elements under GSFC responsibility is ongoing and will continue to be influenced by user input/feedback through meetings with NSIUWG and user disciplin...

|Braided Carbon Fiber Rope Flow Characteristics - Heman, J. R. C|
I am submitting the following technical subject for consideration as a thesis topic for the master degree: The reusable solid rocket motor (RSRM) nozzle internal joints are being evaluated for the incorporation of a carbon fiber rope (CFR) as a thermal barrier. The CFR is approximately 0.260 in. diameter and is composed of approximately 12,000 carbon fibers, woven in ten sheaths or layers. The CFR is manufactured by a sub-tier vendor and subsequently several of its manufacturing details are prop...

This resource contains demonstrations used to illustrate the theory and applications of lasers and optics. Lasers today are being used in an ever-increasing number of applications. In fact, there is hardly a field that has not been touched by the laser. Lasers are playing key roles in the home, office, hospital, factory, outdoors, and theater, as well as in the laboratory.
